TSD250A MEMS Accelerometer
Part #: TSD250A

The TSD250A VMG Transducer is a sensitive accelerometer for use with BIOPAC Vibromyography Systems that use advanced signal analysis algorithms to monitor the small muscle vibrations that occur when a muscle is activated. VMG transducers with software algorithm are optimized for assessing voluntary muscle effort (Type IIb muscle fiber activity). The VMG transducer includes band-pass filtering to eliminate most motion artifacts including physiologic tremor.

Benefits

  • Ability to perform muscle balance assessments
  • Improved reproducibility between muscles and individuals
  • Convenient setup
  • Reduced setup time
  • Improved subject comfort
  • No electrodes
  • No skin preparation

Details

Compatibility


VMG provides extremely reproducible results. The single sensor solution and the lack of skin preparation improve the reliability and reproducibility of muscle effort recordings between muscles and across subjects.

  • This sensor is a replacement for the discontinued TSD250. When comparing multiple subjects identical transducers should be used. Results recorded with a TSD250A may not be directly comparable to TSD250 orTSD251 data.

Interface

MP160: via an adjusted DA100C (5 V excitation voltage) with TCI114 interface. The adjusted DA100C/TCI114 combo is included with VMG Systems for the MP160; it is not included with VMG Systems for the MP36R, transducer only, or software License Packs.
MP36: Direct connection.

Accelerometers can be secured over the muscle belly with a variety of attachment methods (not included), such as double-sided adhesive tape, Ace® bandages and Nylatex® wraps (2.5” or 4” width suggested). Do not use excessive pressure in securing the transducers—snug enough not to move is adequate.

fNIR Imaging Education System

fNIR Imaging Systems are stand-alone functional brain imaging solutions for continuous NIR spectroscopy (NIRS). They provide an in-lab cognitive function assessment and eliminate a great many of the drawbacks of a functional MRI. fNIR optical imaging technology measures neural activity and hemodynamic response in the prefrontal cortex. Subjects wear an fNIR sensor (IR light sources […]
